UNITED STATES PATENT OFFICE.

HENRY AUGUST WETZSTEIN, BROOKLYN, NEW YORK.

.Brooklyn, in the county of Kings and tate of New York, have invented a new and Imclear, and exact description.

This nventlon relates to improvements in tools,-an object of the invention being to rovide a tool, which is primarily designe to facilitate the adjustment of the needle valve onthe carbureter of awell known type of car. In this particular carbureter, the needle valve is provlded with a threaded stem having a tool receivingslot in its upper end and a nut around the stem for adjusting the same. An object of this invention therefore, is to provide a tool which willibe capable ofsimultaneously engaging both the nut and the slot to adjust the valve.

A further object is to provide a tool, which will be of value either in applying or removing any bolt 01' nut in which the bolt head is provided with a tool receiving slot.

Another object is to provide a tool, which will be simple and practical in construction,

strong, durable and eflicient in use, and comparatively inexpensive to manufacture.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a broken view in side. elevation illustrating my improved tool in use;

Fig. 2 is a view in section on the line 2- of Fig. 1.;

Fig. 3 is a reduced broken view in end elevation; and

Fig. 4 is a fragmentary detail view illustrating a modification.

Referring in detail to Figs. 1, 2 and 3 of the drawings, 1 represents a bar having a nut receiving socket such as 2 in one end. 3 represents an angle bracket including a base 4, which is removably secured to the face of the bar 1 and a perforated arm 5 extending in parallelism with the bar 1 and located over the socket 2, the perforation 6 in the arm normally registering with the socket.

A plunger 7 is'mounted in the perforation 6. Any suitable, handle member such as 8 may be provided for operating the plunger Specification-of Letters Patent.

and an outwardly presented annular collar or flange 9 locatedaround theplunger 7 below the arm 5 limits the upward movement .of "the plunger through the arm. A gasket 10 is located around the plunger 7 above the arm; 5 and a coiled expansion spring 11 around the plunger between the handle 8 Q 1 have illustrated in Figs. 1 and 2, the adusting mechanism of a needle valve. 13 represents a threaded valve stem, the position of which, is controlled by a nut 14:. In ad ustlng the stem, the socket 2 receives the nut 14 and theplunger 7 may be depressed untll the tongue 12 engages in a slot 15 in the upper end of the stem. Rotation of the plunger will then operate to turn the stem in the desired direction.

It may be desirable to use the wrench member 1 independentlyof the rest of the tool and therefore the bracket 3 is rer'novably attached to the wrench member. The base 4 of the bracket is provided with a pair of keyhole slots 16 receiving headed studs 17 attached to the member 1. Any approved means may be provided for locking the studs 17 in the narrow ends of the slots 16 so that the plunger 7 will be retained in position directl above the socket 2. I have illustrated in igs. 1, 2 and 3, a spring held pin 18 carried by the bracket 3 and adapted to automatically drop into a recess in the member 1 to lock the plunger in the desired position.

4 lln Fig. 4; l[ have shown a modified form of locking device, in which a pair of spring members 19 are associated with the studs and I the upper faceof the base 20 of the bracket is beveled adjacent each of the keyhole slots, as indicated at 21, so that when the bracket is slid into position, the base 20 will be and the gasket 10 serves to normally v.hold the plunger 1n the elevated and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such slight changes and alterations as falrly fall withing keyhole connected to the bar and including a perforated arm located over the socket, a spring held plunger rotatably supported by the arm, and means normally retaining the bar and the bracket in locked relationship.

2. A'tool' of the character described, comrising a bar having a nut receiving socket -1n one end, an angle bracket including a perforated arm, located over the socket anda base located against the bar, said base havslots therein, studs on the bar movable in the slots,' spring held plunger rotatably supported b the arm, said plunger terminating in a attened lower end.

3. A tool of the character described, coma bar having a nut receiving socket rising end, an angle bracket including 21.

III one erforated arm located over the socket and a ase located against the bar,said base having keyhole slots therein, studs on the bar movable in the slots, a spring held plunger rotatably supported by the arm, said plunger terminating in a flattened lower end, and means for locking the base of the bracket to the bar when theplunger is in alinement with the socket. a

4. A tool of the character described, comrising a bar having a nut receiving socket in one end, an angle bracket including a perforated arm located over the socket and a base located against the bar, said base having keyhole slots therein, studs on the bar movable in the slots, a spring held plunger rotatably supported by the arm,-said plunger terminating in a flattened lower end, and spring, actuated means for locking the base of' thebracket to the bar when the plunger is in alinement with the socket.
